Taxonomy
There had been debate over whether to classify this species as Lynx rufus or Felis rufus as part of a wider issue regarding whether the four species of Lynx should be given their own genus, or be placed as a subgenus of Felis. The Lynx genus is now accepted, and the bobcat is listed as Lynx rufus in modern taxonomic sources.
Johnson et al. reported Lynx shared a clade with the puma, leopard cat (Prionailurus), and domestic cat (Felis) lineages, dated to 7.15 million years ago (mya); Lynx diverged first, approximately 3.24 mya.
The bobcat is believed to have evolved from the Eurasian lynx, which crossed into North America by way of the Bering Land Bridge during the Pleistocene, with progenitors arriving as early as 2.6 mya. The first wave moved into the southern portion of North America, which was soon cut off from the north by glaciers. This population evolved into modern bobcats around 20,000 years ago. A second population arrived from Asia and settled in the north, developing into the modern Canada lynx. Hybridization between the bobcat and the Canada lynx may sometimes occur (see felid hybrid).
